Integrated Headset rattle - please help!(6 posts)

Integrated Headset rattle - please help!RCole
Aug 26, 2002 9:49 PM
I swapped my stem out on my new Merlin (with an integrated Cane Creek headset). And for some reason I cannot get the headset to stop rattling. I "need" to go on a ride tomorrow and need your help! It seems that I cannot get the stem to push the headset firmly into place and I seem to have a bit of a gap. I assume I am supposed to tighten the bolt on/in the top of my Reynolds fork before tightening the bolts on my stem. But when I do this it doesn't seem to push the HS into place. I've never done this before, so thanks for your assistance.

You use a 5 mm key to tighten the plug to the steerer, you use a 6mm key to tension the headset. Make absolutely sure that the clamp on the stem is loose before tensioning the plug. After you have the headset properly adjusted, tighten the steerer clamp of the stem. LoL

Your new stem may not use as much steerer tube( the tube of the stem may not be as tall) and you may have to add a spacer between the stem and headset to use up some steerer length.

Thanks for the responses. It took a lot of pressure to tighten the steerer tube bolt. Is that normal?

No, it's not normal to require a lot of pressure; you're preloading the bearings. As curlybike suggested, your new stem may have less height than your old one. If that's the case, and you managed to get it tight with excess pressure, then you have either crushed the top of the steerer tube, or pulled (slid) the star-nut up the tube. You should compare the stem heights, and if they are different, inspect your steerer tube for damage.
A couple of things. Your new stem should be about 3 mm above thePaul

steerer with everything installed so that when you put on the cap, it will push down on the stem when tightening. If not you get the problem that's been mentioned. Have you installed the Cane Creek bearings correctly? It should just be a little pressure to pre-load the bearings. If you can't figure it out, go to your lbs.

I bet you have a different stack height due to the new stem.
